According to SamMobile’s unnamed sources, Samsung is testing a third variant of the Galaxy Note 4 for South Korean carriers which will feature an upgraded Snapdragon 810 processor. The major difference between the Snapdragon 810 and the Snapdragon 805 that currently sits inside the Note 4 is that the 810 uses a 64-bit octa-core CPU.

The 810 isn’t ready for mass production quite yet, but if Qualcomm can have its latest chip ready by early next year, Samsung might be able to begin producing new Galaxy Note 4 units before even more powerful smartphones make their way to market next year.

Considering the fact that the new Note 4 appears to be exclusive to South Korea (and possibly other foreign markets), it’s highly unlikely that it will have any impact on the popularity of the iPhone 6 Plus in the U.S., so if Samsung plans on combating its shrinking profits, it needs to march forward at a much faster pace.
